Challenge Problems
Push your limits with advanced challenges
If a BJT has a forward bias voltage of 0.7V and the saturation current is 10 microamps, derive the collector current at this voltage assuming exponential behavior.
💡 Hint: Identify what I_S and the exponential factor would imply.
Calculate how a decrease in base width to half affects the transistor's current gain assuming all other variables remain constant.
💡 Hint: Consider the relationship between base width and carrier life.
